Abstract

Palm oil productivity is influenced by many factors. One factor is crop rotation. Harvest rotation greatly influences productivity in oil palm plantations. Obstructed harvest rotation causes the number of fruit bunches to increase in an area compared to the weight of fresh fruit bunches (FFB) harvested. The percentage of brondol in oil palm plantations is very important because it will affect the average bushel weight (BJR) and payments to employees for oil palm plantation companies. The decrease in BJR due to the high percentage of brondol will also have an impact on the morale of workers, especially harvesters on oil palm plantations because the harvest base will be higher to get a harvest premium. This research aims to determine the comparison of the percentage of brondol in various areas, namely hilly, lowland and plain areas and to find out the causes of the high percentage of brondol in the treatment blocks. This research uses an agronomic trait survey method by observing secondary data on productivity and percentage of brondol in the last six years, then analyzed using the t test at a level of 5%.  This research was carried out at PT. Cahaya Nusa Gemilang (CNG) Kenanga Estate garden, Marau District, Ketapang Regency, West Kalimantan. The results of the analysis show that plain areas have the best productivity and percentage of brondol compared to lowland and hilly areas.

Abstract

Coffee is a plantation crop with significant economic value, commonly processed into flavorful beverages. Arabica coffee farmers generally face challenges during harvest and post-harvest, particularly with the necessity to pick ripe, red berries. However, during harvest, farmers often do not selectively pick the cherries, resulting in the collection of not only red but also yellowish or green berries. Plant growth regulators (PGRs) are synthetic chemicals that mimic the role of endogenous hormones. This study aims to investigate the interaction between different hormone types and varieties on the ripening of Arabica coffee berries, assess the impact of various hormones on berry maturity, and evaluate the effect of different varieties on the ripening process. The research utilized a completely randomized design (CRD) with two factors: plant growth regulators (PGRs) and coffee varieties. The observed parameters included the number of fruiting nodes per tree, the number of fruits per node, the number of red fruits in the first harvest, the number of red fruits in each subsequent harvest (across three stages), and the weight of green beans per 100 seeds. The analysis revealed no significant interaction between the application of different types of growth regulators (PGRs) and coffee varieties in accelerating the maturation of Arabica coffee berries. Notably, the Yellow Catura variety treated with the growth regulator Ethrel showed a better effect in accelerating berry maturity.

Abstract

Legume Cover Crop (LCC) used in Palm plantations has not yet produced for weed control because there are still large open lands. To prepare LCC seedling of the Mucuna bracteata species, a medium is required that provides good root growth, inter alia, with the addition of organic material derived from various animal debris. This research aims to find out the influence as well as the interaction of type and comparison of the volume of cage fertilizer on the growth of LCC Mucuna bracteata on the latosol soil that has been carried out at the KP2 INSTIPER, Maguwoharjo, Yogyakarta, Yogyakarta and at the Central Laboratory, Instiper on April 20, 2021 to June 30, 2021. This research uses a complete random design (RAL) or Completely Randomized Design (CRD) method that consists of two factors. The first factor is a type of cage fertilizer that consists of three levels, namely cage, chicken and goat fertilizers. The second factor is the comparison of the volume of the soil of the latosol with the cage of 3 levels of 1:1, 2:1, and 1:2 with 10 repetitions. The results of the study were analysed with the analysis of variance prints at the significance level of 5%. The effective treatment was further tested with the Duncan Multiple Range Test (DMRT) using the significance level of 5%. Results of the analysis showed that the treatment of cage fertilizer and the comparison of the soil volume of latosol with cage fertilizer did not have a real interaction and both treatments gave the same effect on the growth parameters of plants, including its length, leaf number, shoots number, top fresh weight, top dry weight, root length, fresh root weight and dry roots of Mucuna brate plant. Cage fertilizer and volume comparison gives the same bet on all the growth parameters of Mucuna bracteata.

Abstract

Soil respiration is an indicator of the level of soil health in both closed systems (forests) and open systems (agriculture). Conversion of land from natural forest to agricultural cultivation needs attention in the field of sustainability, this is done so that the land can continue to be productive. This research aims to obtain information regarding the relationship between respiration and soil properties in land cover of oil palm (Elaeis guineensis), teak (Tectona grandis), and burflower-tree (Neolamarckia cadamba) in INSTIPER's experimental plantation, specifically in SEAT (Stiper Edu Agro Tourism) Ungaran Regency, Central Java. The method used in this research is a modified Verstraete, namely by observing soil respiration directly on the land. Research data shows respiration rates of 100.1, 95.4, and 25.9 mg CO2 m-2 h-1 for oil palm, burflower-tree, and teak respectively. Soil respiration is influenced by land cover in vegetation. Differences in land cover cause differences in soil properties which then influence the rate of soil respiration. The relationship between soil respiration rate and moisture content, pH, and EC is linear positive, while with volume weight it is linear negative.
